I don't understand how this happened. Apple is a company that built it's empire on paying a premium for reliability and ease of use.

There have been mistakes in the past, but this is something that should have been caught immediately, which suggests that they were aware of it at release.

Is it just nostalgia goggles telling me that Jobs would not have let these out the door?

Apple statement: Following extensive performance testing under numerous workloads, we've identified that there is a missing digital key in the firmware that impacts the thermal management system and could drive clock speeds down under heavy thermal loads on the new MacBook Pro.

That is much more embarrassing than simple thermal throttling of the CPU. The thermal overload on PMIC chips are designed to handle malfunctions not regular usage.

If the voltage regulator is overheating at high CPU load, it must be getting very hot at just normal load. That will seriously reduce it's life span, not to mention a hot voltage regulator means you're pissing away battery unnecessarily.

On TWiT[0]. They had the keyboard up to 115f sometimes, some other videos on youtube have gone much higher. I've also seen a couple of youtubers and the number is growing, returning their macbooks [1], [2], due to the performance and the number is growing daily. I really think this issue is down to a few things. 1) The need from Apple to be thinner each iteration, is really costing them the ability to have better the…

The Apple III had a 100% failure rate because Steve Jobs personally insisted that it have neither cooling fans nor vents.

Similarly, my 2012 Air (8gb RAM, 500gb SSD) is working just fine, and I could probably get quite a few more years out of it.

It astonishes me how well that old laptop does what I need, considering any laptop from 2006 or 2004 would have been slow as molasses in 2012, and total garbage today.

Seems crazy to spend so much on a machine, just have to do something that apparently can void your warranty if something goes amiss, to take advantage of the extra power you paid for.

Well, they do claim to have a firmware fix. https://arstechnica.com/gadgets/2018/07/we-tested-throttling...
